Before ordering

  • Confirm HY53-SE12405-AB against the VIN and current parts catalogue before ordering, especially for 2017–2018 DB11 or 2018 Vantage cars.
  • The supplier description specifies 2019 onward. The model-page generation dates do not establish fitment for every car.
  • No exact NGK, Bosch or Mercedes-Benz equivalent has been verified. Shared M177 engine architecture does not prove spark plug interchangeability.
Evidence for this match

Aston Store identifies HY53-SE12405-AB as a genuine Aston Martin plug and lists DB11 V8 and Vantage V8 applications. Flying Spares independently lists the same base Aston reference. The original supplier manufacturer and its equivalent number remain unverified.
